If you note the baldish player on the right hand side of the pic, he appears to have the war patch on his left sleeve and it's only a sliver of it showing. All of the other players have their arms raised in victory, so we can't tell how many players wore the patch.

As for the player in the blue jersey, my guess is he wore an old blue jersey underneath his regular yellow jersey for additional warmth. It was a bitterly cold day in Cleveland.
